Sensor Electronic Technology, inc. (SETi) is proud to be part of Seoul Semiconductor and Seoul Viosys. Sensor Electronic Technology, Inc. (SETi) is the world’s leading supplier of deep UV LEDs; LEDs with emission wavelengths shorter than 365nm. Using our proprietary and patented technology, we develop, manufacture and sell standard LED products under the UVTOP® trademark and custom LED products and solutions under the UVCLEAN® trademark into public and private sectors. We are committed to meeting and exceeding the needs of our customers and stakeholders through the highest levels of quality management. We develop, manufacture and offer a broad portfolio of UV-A, UV-B and UV-C LED products and application solutions.
Sensor Electronic Technology, Inc’s core technology is based around the growth of AlGaN semiconductor materials. We have developed patented processes, MEMOCVD® and MELEO. These novel processes allow Sensor Electronic Technology to lead the field in high aluminum content AlGaN semiconductors and has enabled us to become the world’s leading manufacturer of Deep UV LEDs.
The electromagnetic spectrum of ultraviolet light can be subdivided in a number of ways. The draft ISO standard on determining solar irradiances(ISO-DIS-21348) describes the UVA(400~315nm), NUV(400~300nm), UVB(315~280nm), MUV(300~200nm) , UVC(280~100nm).
| Nane | Wavelength (nm) | Application | |
|---|---|---|---|
| Near UV | UV-A | 315-400 | UV Curing of polymers and Printer Inks, Blood Gas measurements, Nitrogen urea measurements, Bug zapper, Lighting, Optical Sensing and imaging of dyes, inks and markers and etc. |
| UV-B | 280-315 | UV curing, Phototherapy, Optical Sensing and imaging of dyes, inks and markers. Forensic Analysis, Protein analysis, DNA sequencing, Drug discovery and etc. | |
| Deep UV | UV-C | 100-280 | Disinfection, Ozone Monitoring, Decontamination of surface and water Forensic Analysis, Protein analysis, DNA sequencing, Drug discovery, Optical sensing and Imaging of dyes, inks and markers and etc. |
The LED of UV scope is seeing high efficiency and high output and the industrial use is being proliferated. The UV LED has different application family according to the luminous wavelength and the UV A scope(315-400mm) is mainly used for light firearms, forgery testing machine etc, the UV B scope(280-315mm) is used in medical equipment, analyzing machine and vitamin synthesis etc for medical/bio fields and the UV C scope(280-200mm) is used mainly in the environment field like the sterilization/purification/filtration of water etc.
However, although there are many applications and potential markets like this, the current UV LED light source have difficulties in entering the market due to the difficulties in high quality thin film growth due to the use of AIN family material and the low light output of the UV LED element due to the non-development of element production process technology and absence of the UV LED package element. The market will be magnified with the technological overcoming about the above problems.
